I am using 24 online client from 1 yr as per my experience the service of 24 client is not upto the mark everytime connection drops with out any reason.
Now after using it from so many days the connection stablitity changed now the connection drop is became less but the customer service is very bad when I call them to have query or complain they just sometime just dont give any response pick the call and then end it, so frustrating.
